sybase isql utility with mssql2000

Hi all:

I am running into an issue with MSSQL 2000 that has worked in the past with earlier versions of MSSQL (6.5 > 7). I connect to MSSQL from UNIX via the Sybase's isql utility (which worked in 6.5 and 7) and with MSSQL 2000 I am getting the following error:

DB-LIBRARY error:
Unexpected EOF from SQL Server.

Any thoughts?

I am using sybase isql utility 10.0.4v.

Any help would be much appresaited.

Thanks,
LS
